Any machinery you purchase represents a significant investment for the business, and as such requires proper, regular maintenance to minimise downtime and ensure safe operation. Daily and periodic maintenance are vital for the ongoing lifespan of any machinery, and Monty Products’ range of Montabert Rock Breakers, Surface Drills and Drifters are no different. For day-to-day operation, Montabert recommends the following maintenance checks be performed at the beginning and end of each shift:
- Visual inspection. Check welds for possible cracks on the bracket cap, cradle, tool, and boom (do not weld on the cradle without checking with your dealer).
- Check for loose nuts and bolts in the bracket cap, suspension, accumulator, side plates, tie rods and the wear plates.
- The tool retainer(s). When replacing tool retainer(s), always replace them in sets and rotate them equally. (Service hint: Mark the ends of the retainers to keep track of the rotation order.)
- Hydraulic system. Hydraulic ball valves and quick couplers may be a source of erratic performance and/or cause a rise in hydraulic temperature. Ensure they are 100% open, in good condition, and not leaking oil. Continuously check for oil leaks and any rise in the oil temperature.
- Excessive oil leakage down the tool. This is an indication of worn or damaged seals that need to be replaced.
Montabert recommends performing the following periodic maintenance checks every 100 hours, or more often in severe conditions:
- Remove the tool and all grease from the chuck housing.
- Do not use a pressure washer, steam, or solvents as they damage the seals.
- Check for chips or cracks inside the housing and on bushing surfaces. Cracks and chips could indicate that lubrication is insufficient, grease type is not appropriate, black-firing and side-loading is occurring, or the breaker is being operated improperly.
- Check for wear on tool retainers. Examine the shoulders and side surfaces. If they are worn or deformed, rotate or replace as required.
- Check wear on bushing. Replace the tool, bushing, or both when the combined wear exceeds 4 mm or 3/16”. Some bushings are grooved to provide even grease distribution; light range breakers come with a wear gauge. Replace the bushings when the grooves are worn through. Excessive bushing wear causes tool misalignment to the piston, causing premature breaker failure.
- Replace damaged or worn parts. Wipe all components clean, including the lubrication port. Hand-grease the tool shank and inside the chuck bushings before placing it back into the breaker.
